IONS MONSON, OF NEW YORK, N. Y.

TOB AGCO-PIPE To all whom it may concern:

Be it known that I, J ONS MONSON, a subject of the King of Sweden, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Tobacco-Pipes, of which the following is a specification, reference being had to the accompanying drawmgs.

This invention relates to improvements in tobacco pipes and its object is to provide the pipe with a receptacle for water and tar, and also with means for shutting off communication between the bowl and the stem and opening the inner portion of the smoke passage in the stem so that the latter may be readily cleaned by forcing water or steam through the same.

The object of the invention is to provide a device of this character which will be simple and practical, easy to apply and convenient to manipulate and highly eifective in accomplishing its intended purpose.

With the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a portion of a pipe having the invention applied there to; Figs. 2 and 3 are longitudinal sections through the same, showing the plug or valve member in its two positions; Figs. 1 and 5 are views of the invention removed from the pipe; Fig. 6 is a transverse section; and Figs. 7, 8, 9, 10 are detail views of the ro tary plug or valve memben The invention consists of a socket or casing member 1 and a rotary plug or valve member 2, the latter being arranged within the former and the former being adapted to be screwed or otherwise secured in the bottom of the body or bowl B of the pipe at the point of intersection of the smoke passage 'Z) in the bowl and the smoke passage 8 in the stem S.

The socket member 1 is in the form of a hollow cylindrical body preferably externally screw threaded, as at 3, so that it may be screwed into a recess or cavity formed in the pipe, either While the latter is being made at the factory or by the owner of the pipe. The upper end of the socket member 1 is closed and provided with a small opening l to register with the passage 1) and a similar Specification of Letters Patent.

opening or slot 5 is formed in the rear side of said member to register with the passage 8. The lower end of said member is open and formed upon its exterior with a surrounding flange or enlargement which provides a shoulder to engage the outer surface of the pipe when said socket member is screwed into the latter. Formed in the enlargement, preferably at its front, is a transverse opening 7 and formed in its outer surface opposite said opening is a groove 8. The latter is of semi-circular form and extends half-way around the member or from one side to the other of the socket member and said groove 8 is intersected at its center by a vertical groove 9 which is disposed at the rear or diametrically opposite the opening 7 and extends downwardly from the groove to the bottom face of the socket member.

The rotary plug or valve member 2 is in the form of a solid cylindrical plug rotatably and removably mounted in the socket mem' ber and having at its lower end an annular flange or enlargement 10 which engages the bottom edge of the enlargement or flange on the socket member. Said plug member is retained in the socket member by providing upon its bottom an upwardly and inwardly extending finger or projection 11 adapted to enter the groove 8, as shown. Said groove extending half-way around the socket member is adapted to permit the plug member to make a half rotation in said socket member and when said plug member is in an intermediate position the finger 11 is adapted to register with the intersecting groove 9 so that the plug member may be removed from the socket member. Said finger or projection 11 may be formed integral with the plug member, as shown in the first eight figures of the drawings, or it may be formed on a separate strip of metal 12 and secured by fastenings 13, as shown in Fig. 10.

The cylindrical body of the plug member which rotates in the socket or bore of the socket member, is formed at a suitable distance from its upper end with an external annular groove or channel 15 and two longitudinally or vertically extending recesses 16, 17, so that said body somewhat resembles a bobbin. The recesses 16, 17 are arranged upon the opposite sides of the body or plug, the recess 16 extending upwardly from the annular recess or channel 15 to the top of the body and the other recess 17 extending in the opposite direction or downwardly a distance sufficient to permit its lower end to be brought opposite the opening 7 in the socket member. By constructing the plug member in this manner, it will be seen that when it is in position in the socket member and the retaining finger 11 is turned to one end of the groove 8, the recess 16 will register with the passage band the recess 17 with the passage 8, while theopening 7 will be closed by the solid portion of the plug, as clearly shown in Fig. 2, in order that the smoke in the bowl of the pipe may pass through the passage Z), the opening 4, the recesses 16, 15, 17, the opening 5 and the bore or passage 8; and when said plug member is turned so that its finger 11 is at the opposite end of the groove 8 the solid upper portion of the plug member will close the opening a while the recess 16 is brought into register with the opening 5 and the recess 17 into register with the opening 7, as shown iirFig. 3, in order that when the mouth piece or stem of the pipe is held to a water faucet, water may pass through the passage 8, the opening 5, the recesses 17, 15, 16 and out through the opening 7 thereby permitting the stem of the pipe and the several parts of the invention to be effectively cleaned without removal from the pipe and without the use of extraneous cleaning devices.

By constructing the plug member with all the recesses exposed, it will. be seen that it may be easily and effectively cleaned when removed from the socket member and that owing to the manner in which it is retained in the latter, it may be quickly and easily removed.

lVhile the preferred embodiment of the invention is shown and described in detail, it will be understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
